Rated 5 out of 5 bycourtier from Very smooth and easy installationI've used a number of USB to serial adapters with my Mac over the years. Each couple of OSX updates seems to break support and require new software and/or drivers. This unit installed easily and worked right away whereas many other ones I have failed to work under the current OS (Yosemite 10.10.2).

Rated 5 out of 5 byhowardh from USB to Serial Adapter Cable (USB-A to DB9 M/M) 5-ft.Our organization uses amateur radio for redundant communications. Part of those communications utilize RMS Express. In order to connect our laptops to the radios we now only use the Tripp-Lite U209-000-R. The drivers load quickly and we don't have to worry about making sure that we have the same cable with the exact same radio. We have tried a number of other connectors over the years, but none deliver the consistency and reliability of the Tripp-Lite. When an emergency strikes, it is good to know that we can still communicate no matter what happens. Thanks, Tripp-Lite!

Rated 5 out of 5 byMJ from Filled our needs completelyIn our environment, sometimes we run into older machines needing access to newer technology or vice versa. This product was purchase to be used in a scientific lab and we were very happy with the results. Drivers loaded very easily, and communication was established without error.

Rated 5 out of 5 byJon from Great ProductI recently upgraded my computer. Now I have no 9 pin serial port. I needed to interface with a gas monitor to download logged data. I plugged in the U209-000-R and it connected immediately with no problems. It is a great product.

Rated 5 out of 5 byErik the IT Analyst from We have ordered this product over 60 times and counting!We have used this item over 60 times in different clinics. Since first purchase, we have never found a need to replace them. The driver takes seconds to install, and the connection to our lab equipment has been seamless. The only concern is the Serial end only has Male connectors. Our adapter for lab equipment is also Male, so we have to work a little harder for cable management. From a functionality front, we wouldn't change a thing!
